Battery Visual Inspection (1)

1. Ensure that the battery electrolyte level is between A and B shown in the figure. Add if the level is lower than the specified range.
2. Use a hydrometer and temperature gauge to check the specific gravity of the electrolyte.

   Standard value: 1.220 - 1.290 [ at 20°C (68°F)] 

The specific gravity of electrolyte depends on its temperature. Use the formula below to determine the proper value.

Conversion on centigrade 

D ₂₀  =(t - 20) x 0.0007 + Dt 

Conversion on Fahrenheit 

D ₂₀  =(t - 68) x 0.0007 + Dt 

D₂₀ : Specific gravity as if electrolyte temperature is 20°C (68°F)

D_t : Measured specific gravity

t : Measured temperature
